Tentative Design

curtain stays in place and therefore eats input until screen is entirely unblanked

status indicators may reveal single menu for:

- possibly input language - volume - battery - network

lock is removed by:

- dragging up with pointer or touch - scrolling up with mouse wheel - Esc key on keyboards

Comments

Having the user's name appear in the top-left corner of the lock screen is inconsistent with the default Gnome Shell layout, where the name is in the top-right corner. I can't see any reason why the name should be moved to the other side of the screen!
